Question

explain how to count the number of elements in a compound.

Explanation:

To count the number of elements in a compound, first identify the chemical formula of the compound. Each capital letter in the formula represents a different element. For example, in \(H_2O\), \(H\) (hydrogen) and \(O\) (oxygen) are two elements. If there are sub - scripts (e.g., \(H_2O\) has a sub - script \(2\) for \(H\)), they only indicate the number of atoms of that particular element, not a new element. So, simply count the distinct capital - letter - starting groups in the chemical formula.

Answer:

Count the distinct capital - letter - starting groups in the compound's chemical formula.
